Section 106 of the National Historic Preservation Act (106) indicates that Federal Agencies need to take into account the effect of Federal undertakings on historic properties. A Federal "undertaking" is defined in the National Historic Preservation Act of 1966, as amended, Section 301(7) as; 

"Undertaking" means any project, activity, or program funded in whole or in part under the direct or indirect jurisdiction of a Federal agency, including-- 


A. those carried out by or on behalf of the agency; 

B. those carried out with Federal financial assistance; 

C. those requiring a Federal permit, license, or approval; and

D. those subject to State or local regulation administered pursuant to a delegation or approval by a Federal agency. 


As part of the identification effort required under the Advisory Council's Regulations 36 CFR 800.4(a), it is the policy of the Wyoming SHPO to require a Class III 100% intensive inventory of all Areas of Potential Effect (APE) for projects except in the instances listed below. 



The above situations exempt a project from a Class III survey, but not from compliance with Section 106 and 36 CFR Part 800. 

For all undertakings, a Class I inventory (file and literature search) must be conducted by the agency or a qualified cultural resource consultant in order to meet the requirements of 36 CFR Part 800.4(A)(1). If known historic properties are located in the file search, additional field work in the form of site relocation, National Register of Historic Places evaluation, determination of effects and development and implementation of mitigation plans may be necessary to meet the requirements of Section 106. 

If the Federal Agency determines that the undertaking does not require a Class III Survey, the Federal Agency shall initiate consultation with SHPO by furnishing SHPO with the appropriate documentation. This documentation will include, but is not limited to, the following:
